SEPARATOR.

. This invention relates to means for climinating moisture and, solids from fluid streams that are derived from pressure drums, pipes and conduits. There are many cases in which large pipes serve to conduct pressure fluids to numerous points of take off and use. Familiar cases are found in the instances of steam and compressed air lines from which many smaller pipes lead to various places of use. I find that in such cases it is unwise to depend wholly upon a single separator or even several separators in the main line. Instead I provide each olftake with its own eliminator or separator directly at the point of oiftake and in such manner as to throw the intercepted substances back into the reservoir or main line. Such is the purpose of this in- 'vention; to which is added the object of providing separator units of such small size and cost as to admit of their general employment throughout any pressure system. The invention will be readily understood on reference to the drawings that'form part of the specification; in which, Fig. 1 is a longitudinal section of a novel separator embodying my invention; Figs. 2, 3, 4 and 5 are cross sections upon the lines ,2-2, 4-4, and 5-5 of Fig. 1; Fig. 2 being a view from the position of the arrow 2 in Fig. 1; and Fig. 3 a View in the direction of the arrow 3; Fig. 6 illustrates the novel combination of the separator with a stop valve; Fig. 7 illustrates the novel method of applying several of these separators to a main line or. conduit; and, Fig. 8 shows still another method of applying the device. The part 2 in Fig. 1 may be taken as representing the top of a pressure drum or the top of a pipe, such as that shown in Fig. 7. The part 3 is a threaded pipe plug, having a central hole 3 and receiving the oiftake pipe at. The lower end 5 of the plug 3 is of reduced size and preferably has a groove 6. The extreme end 7 of the plug is preferably in the form of a truncated cone, flaring outward and upward. The part 8 which hangs from the plug portion 5 is a multiply tuyered ring or barrel char- M) as part 2, so that the device as a whole may be acterized by many tangential blade portions 8 and as many tangential fluid entrance,

inserted and withdrawn whenever necessary. .The part 9 1s a tuyere-end or closure, which preferably rises considerably above the open lower ends of the open tuyeres 8".

In aggregate area the tuyeres 8 very considerably exceed the cross sectional area of the outlet or hole 3 inthe plug 8. Obviously, the hole 3 is the passage through which the fluid passes from the drum or conduit. I

It will now be clear that the tuyere hangs inside the drum or conduit containing the pressure fluid. The fluid seeking to escape through the outlet 3 must first pass through the many tangential tuyeres 8. It is thereby set into very rapid rotation within' the cylindrical space 10 between the parts 9 and 7. The eifect of the rotation ,is to centrifugally separate the heavier substances carried by the fluid and as the portion 7 prevents their escape into the outlet 3 they whirl to the bottom and drain back into the drum or conduit over the edge or periphery of the closure 9.

Most conveniently the tuyere ring or bar rel is stamped and formed from sheet metal, or from a metal tube. The upper end 8 of the tuyere ring slips onto the part 5 and may either be welded in that position or clinched into the groove 6.

In extending the usefulness of the invention I have combined the pipe plug and tuyere with the casing 10 of a stop valve 11, as represented in Fig. 6.

My invention also comprehends the structure shown in Fig. 7 whereby a pipe or conduit is adapted to receive separator plugs of different sizes and further is provided with collection pockets 12. The use of cross couplings 13 and Ts 13 in the main conduit 14 9 ofltake from a drum or conduit and containing an axial outlet passage, the inner end of said plug being reduced in diameter and shouldered concentrically with said axial passage, in combination with a tangentially tuyered barrel having one end attached to his! and part-ially'closed by the reduced shouldered end of said plug, the external diameter 01 said. barrel being slightly less than the diameter of the body of said plug, and the inner diameter of said barrel being so much greater than that of the said passage as to present an annular abutment, and, a dis0- like member closing the free end of said barrel.

2. A reducer plug having a central passage and having a reduced and shouldered end having a tuyere retaining groove in corn bination With a multiple tangentially tuyered barrel fitting said reduced end, and

raving its own end interlocked in the groove of the plug, and a disc-like member closing the free end of said barrel. 7

3. A reducer plug containing a central passage and having a tuyere retaining groove, in combination with a multiple tangentially tuyered barrel having its end positioned in the groove of said plug, and the inner diameter of said barrel being greater than the diameter of said central passage as described.

In testimonywhereof I have hereunto set my hand this 30th day of April, A. D. 1925.
